This is Part 4 over 6 of “Coding for SSDs”, covering Sections 5 and 6. For other parts and sections, you can refer to the Table to Contents. This is a series of articles that I wrote to share what I learned while documenting myself on SSDs, and on how to make code perform well on SSDs. If you’re in a rush, you can also go directly to Part 6, which is summarizing the content from all the other parts.
In this part, I cover briefly some of the main SSD functionalities such as TRIM and over-provisioning. I am also presenting the different levels of internal parallelism in an SSD, and the concept of clustered block.
